Peugeot Activity has disclosed further info about the powertrain it will use in its challenger for the future Le Mans Hypercar course from the 2022 Globe Stamina Championship period.
The petrol/electric powered hybrid drivetrain is dubbed Peugeot HYBRID4 500KW. As the identify indicates, 500Kw – which is 671bhp – is on offer, from a 2.six-litre twin turbocharged 90-degree V6 petrol motor. The mid-mounted unit weighs 165kg – for reference, the 1.six-litre V6 energy models in Formulation 1 have a least body weight of 150kg, though this also contains the vitality restoration methods. The Peugeot’s V6 sends push to the rear wheels as a result of a seven-pace sequential transmission.
The petrol motor is backed up by an electric powered motor driving the front axle. This produces 268bhp and is run by vitality stored in a 900-volt battery sitting down right in the centre of the car, between driver and V6, and beneath the gas tank.
Right before the race, this battery can be billed by way of a plug. Though it’s on monitor, vitality is recovered as a result of regenerative braking, created doable by a brake-by-wire program which will let the drivers to alter the bias between electric powered motor braking and a classic hydraulic setup of discs and pads on the fly.
Though the mixed output of those people models is 938bhp, the new policies in the Globe Stamina Championship Hypercar course condition that only a most of 671bhp is ever employed. In most predicaments, the petrol unit will thus operate at 402bhp, with the rest of the energy equipped by the electric powered motor.
Electric powered motor usage is forbidden under 75mph – this is to avert a 4-wheel push traction gain about cars crafted to the competing LMDh rules, whose hybrid powertrains are rear-wheel push only – so the petrol motor can run at a higher output at lower speeds. The V6 can also produce the entire 671bhp when the hybrid battery is depleted.
The tech specs observe on from a sequence of sketches which expose the wild aerodynamic offer that the three-time 24 Several hours of Le Mans-successful outfit could operate. Even so, it also displays that Peugeot road car cues, like the claw-like three slash lighting models front and rear, will also feature.
The new hypercar rules necessarily mean the cars will develop relative to the LMP1 policies at the moment in place in the major tier of WEC groups. The five-metre over-all size is 35cm for a longer time than LMP1 rules let, while the width is up 10cm to two metres.
Speaking of the announcement, Peugeot CEO Jean Philippe Imparato reported: “Le Mans is the holy grail of the automobile entire world. We are coming back again to endurance racing for the reason that we have the opportunity to get the job done the sport in a different way, with the hybridization of fuel and electric power.”
Peugeot Activity will begin entire tests to the end of 2021, with powertrain bench tests and simulator get the job done underway before in the year.
